Parameter Description MD280/MD280N User Manual
- 110 -
signal specification: voltage range: 9V to 30V; frequency range: 0kHz to
50kHz.
When the frequency source is “PULSE reference (DI5), pulse reference
can only be input via the multifunctional input terminal DI5 and DI5 is pulse
frequency input function terminal by default and other settings are not
required.
Caution: When DI5 is used as pulse input, it needs to set the input terminal
DI5 to 0 (no function) so as to avoid triggering error action.
4: MS speed
Select MS speed running mode. It needs to set Group F2 “Input Terminals”
(F2-00 to F2-04) and MS reference parameters of Group F8 “MS Speed
and PLC” (F8-00 to F8-08) to determine the corresponding relationship
between the terminal reference signal and the reference frequency.
For details regarding the function setting of terminals and MS speed, refer
to the function description of “MS Speed Terminal” of input terminal DI of
Group F2.
5. PLC
Select simple PLC mode. When the frequency source is simple PLC, it
needs to set the parameters of Group F8 “MS Speed and PLC” to
determine the reference frequency at each running phase. Refer to the
description of Group F8 function codes for the PLC running setup.
6: PID
Select PID process control.In this case, it needs to set Group F6 “PID
Function”. Inverter operation frequency is the frequency after PID
reacts.Refer to “PID Function” settings in Group F6 for meanings of PID
reference source, reference parameter, and feedback source, etc.
7: AI1 +AI2
It means that the frequency is given by adding the setting value of input
terminal AI1 to the setting value of AI2. Refer to the description of Group F2
function codes (F2-08 to F2-19) for the settings of AI1 and AI2 input
frequencies.
8: Communication reference
The frequency source is given by the host computer via the communication
